The compatibility of current alginate impression materials and dental stone is not completely understood. The purpose of the present study was to determine compatibility of commercially available alginate impression materials dental stones. A stainless steel die certified according to ISO specification No.1563 was used to make specimens for evaluation of surface detail. The mixed alginate impression was poured into a ring mold, and the test block was pressed down onto the material, and then removed after the material is set. The dental stones were mixed according to manufacturer’s instructions. The mixed dental stone was added to the impression in small increments. The casts were allowed to set for 1 hour at ambient room temperature of 20°C +- 2°C and 50% +- 10% relative humidity. The casts were examined under low angle light at X 10 magnification with a stereo zoom microscope (Motic MLC-150C Microscope Cold Light Source) for the entirety of the 0.05-mm-wide line. Among the fifteen combination we found that Neocolloid and Elite model found the best at significance level (p = 0.05). Hydrogum 5 and Elite rock shows the 2nd best combination and Hydrogum 5 and Elite model shows the third best combination. The results of this study should be used as a guide in determining compatible impression materials and dental stone.
